The back end servers include SQL Server clusters (four serversin two clusters), two Microsoft Windows 2000 Active Directorydomain controllers, a MOM monitoring server, an imaging andinstallation server, a backup server, and an HTML transformationserver. These servers form a private network and do not have directInternet access, so the Back End network is private.

All Front End servers are also dual-homed on the Back Endnetwork. To be more secure, you can use a router or firewall toconnect Front End and Back End networks. The Back End network usesthe following IP addresses:
